BACKGROUND

Field

The present invention relates to a method, a system, and a computer readable recording medium for searching game challenge opponents based on an action of a user, and more particularly, to a method, a system, and a computer readable recording medium for searching game challenge opponents based on a user selecting a “challenge to neighboring persons” to search for challenge opponents, searching, and providing the neighboring persons as challenge subjects by an action of a user terminal, through a game service platform providing a plurality of game services.

Discussion of the Background

A smart phone is an intelligent cellular phone having computer support functions added to the cellular phone. The smart phone has a personal digital assistant (PDA) function, the Internet function, a moving picture reproducing function, and the like, added thereto while satisfying cellular phone functions. The smart phone includes various input schemes and touch screens to provide an interface that is more convenient for use. Since the smart phone supports a wireless Internet, it also accesses the Internet and a computer to perform as a terminal, such as an E-mail application, a web browsing application, a fax application, a banking application, a game application, and the like. The smart phone also has a standardized operating System (OS) or a dedicated operating system in order to accommodate various applications.

As implementation of various applications has been enabled through various user terminals, such as, the smart phone and the like. Various application programs and contents for the user terminal apparatus have been developed. As the applications of the user terminals have been improved and many mobile games are played in an environment similar to a web environment have been developed. Therefore, many network games in which users accessing a network through their user terminals may play the same game together have been developed. In this case, generally, game clients are deployed in user terminals or client terminals (for example, smart phones) and connected with each game server through a wired and wireless communication network to perform a corresponding game on the user terminals.

Korean Patent Laid-Open Publication No. 2003-0088621 (entitled “SYSTEM FOR CONNECTING WIRELESS GAME BY CONDITION MATCHING OF PARTICIPANT AND SMS AND METHOD THEREFOR)” to WISPOST, INC describes technology of connecting the same game among smart phone users through the wireless Internet (Document 1). Document 1 describes a game relaying system for informing unspecified users that intend to participate in a game in the wireless Internet by a short message service (SMS). The unspecified users may participate in the game when conditions of the unspecified users match and immediately connecting recipients with each other when the recipients participate in the game.

The technology of Document 1 has problem: participation in the game is possible only when a real time battle among matched game participants is possible; and when the game connection is not made in real time due to a time delay or the like, the user is required to wait for a short message service response or the like frequently. Since a battle with an opponent ends only at the time of each connection, a record may not be updated in a game or the like, where a game victory or defeat is determined through a repetitive record such as a recording game or the like. Therefore, record updating is problematic. Further, since the matching with the game opponent is implemented only in a specific game, it is impossible to play another kind of game or match with a user that has not played a corresponding game.

Furthermore, the method for matching a battle opponent according to the related art includes a series of processes in which the user accesses a server, searches another user in the server, and seeks an agreement in order to provide information on another user that the user wants to form a connection with, which is troublesome, requires a high cost, and requires a large amount of time in an information provision and agreement process.

A method and a system for providing a game through a connection with a challenge opponent capable of providing a game by selecting a challenge game and a challenge opponent is disclosed. A game challenge to the selected opponent on a game service platform managing a game service in interconnection with a plurality of games is disclosed. Particularly, the present invention suggests a method and a system for searching game challenge opponents, for example, with an action of generating a motion, such as, a motion in which a user shakes his/her user terminal or allows his/her user terminal to collide with an opponent's user terminal on a game service platform. A game record among users simultaneously moving their user terminals may be confirmed through matching. Other users providing confirmation by shaking their user terminals at the same time may be searched and selected as challenge opponents. When the user terminal is shaken, position information of the user may be confirmed and other users subscribing to a neighboring game service platform may be recommended.

A method of searching game challenge opponent candidates and selecting a challenge opponent among the searched challenge opponent candidates is performed on the game service platform interconnected with the plurality of games. One can select a specific game among the plurality games provided on the game service platform before determining the challenge opponent. The challenge opponent may be a user that has experienced or installed the selected game or a user that has experienced another game on the game service platform but has not experienced the selected game. When the selected game is not installed in the user terminal of the challenge opponent a procedure of automatically downloading and installing installation software of the game may be added.

A challenge proposer may set the number of challenge opponents and a challenge period. The game can be performed several times during the challenge period, thereby generating a competitive spirit among the challengers. The present teachings may also be applied to a record game played by the respective challengers to calculate records rather than the game played in real time among the challenge opponents. Records updated by the respective challengers during the challenge period may be reported in real time to the user terminals, for example, smart phones, of other challengers and/or the challenge proposer.

When the challenge period has ended, a challenge result may be provided to the user terminals of the players and the players may directly inquire and view the challenge result. A predetermined point or various kinds of benefits may be provided to the players according to the challenge result.

Information related to the challenge may be interconnected with a Social Network Service (“SNS”) to be shared through a corresponding SNS page. By using the SNS service a human network among the respective game users may be expanded.

A method for selecting challenge opponents may be variously implemented. For example, the server may match rivals to an ability of a user and recommend matched rivals as the challenge opponents or search other users positioned in the vicinity of the user, or the user may select friends registered by him/her as the challenge opponents. Further, the server may also randomly use these various methods to determine and provide opponents.

A method for searching for other users positioned in the user's vicinity is provided. The other users are searched using position information of the user terminal, distance information set by the user, time information, and the like.

The following disclosure uses the term “smart phone.” However, the present invention may be applied to any user terminal capable of providing a function of the present invention including all user terminals capable of executing an application, including a fixed terminal such as a computer, a television, or the like, as well as a mobile terminal such as a cellular phone, a laptop computer, a digital broadcasting terminal, a personal digital assistant (PDA), a portable multimedia player (PMP), a navigation apparatus, or the like.

A game service user may access a plurality of games through the game service platform to play the games. The game service platform integrates and manages the plurality of games and provides a channel capable to selecting and playing the respective games to the service user.

The service user selects a specific game and selects an opponent to challenge through the game service platform. The opponent receiving the challenge proposal may or may not accept the challenge proposal.

A challenge room corresponding to the challenge is generated, and the service user that has proposed the challenge and the opponent that has accepted the challenge are registered in the challenge room. With the challenge room, a play result of the corresponding game is managed and various services related to the challenge are provided. An opponent that has not accepted the challenge may also be registered in the challenge room, such that the same challenge procedure may progress with respect to the opponent that has not accepted the challenge. Processing for the challenge result may not be provided to the opponent that has not accepted the challenge.

The service user may set the number of challengers and a challenge period with respect to one challenge. The service user may propose the challenge to a plurality of opponents. A plurality of challenge rooms may be generated with respect to the same game and a plurality of challenge rooms may be generated according to several challenge proposals at the same time with respect to each of a plurality of games.

FIG. 2 illustrates a menu implementation through a game service platform according to exemplary embodiments. After log-in is completed through a home menu 200 of the game service platform (or a home menu of a challenge service), various menus capable of searching challenge opponents may be displayed as shown in FIG. 6.

When a challenge proposal selects the challenge opponent search menus to search the challenge opponents and select a specific opponent as a challenge subject, the challenge proposal is executed. The challenge proposer sets various parameters, for example, the number of challenge participants, a challenge progress period, and the like, on the challenge. The challenge opponent receiving the challenge proposal may accept or reject the challenge proposal, confirm a challenge invitation as shown in FIG. 9, and start the challenge.

When the challenge starts the challenge room is generated. A record for the challenge is managed as the challenge progresses. A challenge result is generated after the challenge ends, such that the challenge result may be transmitted to or viewed by the challenge participants. The challenge result is interconnected with the SNS service so that information may be shared.

A method of searching and challenging the challenge opponent may be variously implemented. The method of searching and challenging the challenge opponent may be implemented with various methods, such as, a challenge to rival 210, a challenge to neighboring person 220, a challenge to my friend 230, a challenge to fateful opponent 240, and the like. The “challenge to rival” menu 210 searches and recommends persons having a game ability similar to a game ability of the service user. The “challenge to neighboring person” menu 220 searches and recommends users positioned in the vicinity using position information of the user terminal. The “challenge to my friend” menu 230 searches and recommends friends for the service user in, for example, the game service platform, the challenge service, the games, an address book, or a phone book. The “challenge to fateful opponent” menu 240 randomly selects one of the search methods described and recommends a challenger. When the “challenge to neighboring person” menu 220 is selected, a motion of the user terminal is sensed and neighboring users are searched using their position information or the like, thereby making it possible to execute the game challenge.

A profile menu 250 capable of viewing and correcting various profiles of the service user, a guide menu 260 to guide a service, and a setting menu 270 to change various settings can be provided.

The game record managing unit 414 performs a function of managing the respective game records related to the challenge of the corresponding members, or all game records.

The game interworking module 420 may include an individual game accessing unit 421, a log-in managing unit 422, a charging processing unit 423, a game software (S/W) installing unit 424, and the like. The individual game accessing unit 421 accesses a specific game when the specific game is selected among a plurality of games provided in the game server 302 interworking with the game service platform server 301. The log-in managing unit 422 integrates and processes log-ins of the games or the log-ins of the games when the users access the games through the game service platform. The charging processing unit 423 charges for a specific game by interworking with the payment server 304 when the specific game is a paid game. The game S/W installing unit 424 is executed by a challenge acceptance processing unit 434 to proceed to a game S/W installing step and then install S/W of the corresponding game, when the S/W of the corresponding game is not installed in the client terminal when the user receiving the challenge proposal accepts the challenge or when the user accepts the challenge and intends to access the corresponding game according to the exemplary embodiment of the present invention.

The game challenge managing module 430 may include a challenge managing unit 431, a search method selecting unit 432, a challenge proposal processing unit 433, a challenge acceptance processing unit 434, a challenge notification processing unit 435, and the like. The challenge managing unit 431 performs processing related to the challenge progressed according to the exemplary embodiment of the present invention. Particularly, the challenge managing unit 431 receives challenge related information, for example, the number of challengers, a challenge period, a challenge object, and the like, set by the challenge proposer, and stores and manages them in the challenge information database 455.

The search method selecting unit 432 provides an interface so that the user (the challenge proposer) selects one of various challenge opponent search methods and receives a selection signal for the search method input to command the challenge opponent search module 440 to perform the search according to the selected search method. The challenge opponent can be a user accepting the game challenge to play the game, only members installing at least one game may be searched as the challenge opponents. However, the challenge proposer is not limited to the members installing the selected game. When the challenge proposer only installs the selected corresponding game and has not yet played the game once game record information is not present and a game level of the challenge opponent may not be present. Record information (game level) of the challenge proposer for the corresponding game may be confirmed, and record information (game level) of the challenge opponent may be set to be positioned in a range set from the record information (game level) of the challenge proposer by, for example, increasing the game level of the challenge proposal by 10% or adding 10 to the game level of the challenge proposer. The record information (game level) arbitrarily set as described above may be used when the challenge proposer selects the “challenge to rival” item.

The challenge proposal processing unit 433 processes the challenge proposal to a specific user when the specific user among users (that, challenge opponent candidates) searched through the challenge opponent search module 440 is selected as the challenge opponent. For example, the challenge proposal processing unit 433 displays the challenge proposal by transmitting a message to the selected challenge opponent, transmitting an alarm, or generating a pop-up window, and discards the challenge proposal when acceptance for the challenge proposal is not processed in a set period. The challenge acceptance processing unit 434 processes the challenge acceptance, when the challenge is proposed through the challenge proposal processing unit 433. The challenge acceptance processing unit 434 registers the user accepting the challenge as the challenge opponent in the corresponding challenge room. The challenge acceptance processing unit 434 may confirm whether or not the game for the challenge has been installed in the user terminal and allow the game to be downloaded through the game S/W installing unit 424. A method of downloading the game includes a method of providing a link allowing the game to be downloaded directly from a server, a method of performing a direct connection with the corresponding link, a method of executing a program capable of downloading the corresponding game, such as iTunes or Android market, or the like, but is not limited thereto. After the game is downloaded, the processing for the challenge acceptance is again performed. The challenge notification processing unit 435 performs notification processing to the user terminals of the corresponding challenge proposer and/or the respective challenge opponents through various means (for example, a pop-up window, a message, a short message, an image of a background screen, a text, an alarm, and the like) at the time of occurrence of various events (for example, challenge start, challenge end, record updating, object accomplishment, and the like) related to the challenge progress when the challenge starts.

As described above, the units of the game challenge managing module 430 provide various features related to the challenge progress by various methods.

The challenge opponent search module 440 receives selection information for a specific search method from the search method selecting unit 432 of the game challenge managing module 430 and searching for the challenge opponent according to the corresponding search method.

For example, when the challenge proposer selects the “challenge to rival” item, a rival searching unit 441 searches users having ability or record that is the most similar to that of the challenge proposer and displays the search result. The record information of the challenge proposer for the corresponding game is confirmed through the record information database 454, and the users having the record in the set range based on the confirmed record information are searched and output.

When the challenge proposer selects the “challenge to neighboring person”, a neighboring person searching unit 442 confirms position information of the user terminal, searches for users positioned closest to the challenge proposer among members accessing the service platform, and displays the search result.

When the challenge proposer selects the “challenge to my friend”, a my friend searching unit 433 searches game friends registered through the friend registration managing unit 413 and displays the search result or searches friends stored in an address book or a phone book and displays the search result. In addition, when the challenge proposer selects the “challenge to fateful opponent,” a fateful opponent searching unit 444 randomly selects one of the above-mentioned search methods to search users and display the search result.

The additional processing modules (not shown) may include an SNS interworking processing unit, a message transmission processing unit, an advertisement providing unit, and the like, so as to provide functions added to the function of the game challenge managing module 430 or various additional functions provided by the game service platform according to the exemplary embodiment of the present invention.

First, the user of the client terminal 320 (for example, the smart phone) downloads and installs the game platform software (S501) and drives the installed game service platform (S502). After the game service platform is driven, when member subscription and log-in are performed (S503), the home menu of FIG. 2 may be displayed on the client terminal 320.

Then, according to the exemplary embodiment of the present invention, the challenge opponent is searched to select a selectable menu (S504), thereby starting the challenge. For example, the challenge opponent search method such as the “challenge to game rival” (See FIG. 7), the “challenge to neighboring person” (See FIG. 8), the “challenge to my friend” (See FIG. 9), the “challenge to fateful opponent” (See FIG. 10), or the like, may be selected.

When the challenge opponent search method is selected, the game to challenge is selected in the respective challenge opponent search menus (S505), information (for example, the number of challenge participants, a challenge time, a challenge object, and the like) related to the corresponding challenge is set (S506), and the challenge opponent search (S507) is executed.

When the search is performed according to the execution of the challenge opponent search and a search result is not present, the procedure of providing a game may return to the challenge opponent selection menu (S504) to search again for the challenge opponent. When at least one user is located as the challenge opponent search result, a specific user is selected as the challenge opponent (S509).

After challenge proposal information is transmitted to the corresponding user according to the challenge proposal and the user receiving the challenge proposal accepts the challenge (S510), the user accepting the challenge is added to the challenge room (S511) to perform the challenge together.

As the challenge starts, challenge progress situations (for example, record updating, ranking change, object accomplishment, and the like) are notified to the challenges in real time (S512), thereby making it possible to stimulate a desire of the challenge participants to win. After the set challenge time elapses and the challenge ends (S513), the challenge result is notified to the challenge participants (S514).

Although not shown in FIGS. 5A and 5B, when the game for the challenge is not installed in the user terminal of the user accepting the challenge, a procedure of downloading and installing the corresponding game in various schemes may be added.

As described above, a specific game is selected through the game service platform, and the challenge is proposed and accepted, thereby making it possible to provide the challenge service. The above-mentioned process is performed, makes it possible to doubly increase an interest in the game. The challenge opponent is added as the game friend and expands the human network. Since a challenge period may be set and the game challenge may be performed several times in the corresponding challenge period, the present invention may also be applied to the case of the record game that is not a battle by real-time access. Record situations of the challenge participants are notified to the challenger participants in real time during the challenge progress, thereby making it possible to stimulate a desire of the challenge participants to win.

Search Algorithm for Challenging to Neighboring Person

Hereinafter, a method for searching neighboring persons for a game challenge according to exemplary embodiments of the present invention will be described with reference to FIGS. 13 to 20.

FIG. 13 illustrates a concept of searching game challenge opponents based on an action of a user according to exemplary embodiments of the present invention. When the user shakes the user terminal 1310 in the “challenge to neighboring person” state illustrated in FIG. 7B, challenge opponent search request information is transmitted to the game service platform server 301, and the challenge opponent search module 440 conducts a search to locate another user terminal 1320 shaken at the same time in the vicinity according to the search request and recommends a user of another user terminal 1320 as a challenge opponent.

When a first user of a first user terminal 1310 and a second user of a second user terminal 1320 make a game challenge to each other, the first and second users may perform an action such as shaking the first and second user terminals 1310 and 1320 or bumping the first and second user terminals 1310 and 1320 against each other.

In this case, the first and second user terminals 1310 and 1320 may sense the action (the motion) thereof by a sensor (for example, a gravity sensor, a terrestrial magnetism sensor, an acceleration sensor, or a gyro sensor) and provide the challenge opponent search request generated according to the motion to the game service platform server 301.

The game service platform server 301 may obtain position information of the first user terminal 1310 according to the request received from the first user terminal 1310 and distance information set by the first user. The game service platform server 301 may obtain position information of the second user terminal 1320 according to the request received from the second user terminal 1320 and distance information set by the second user.

The game service platform server 301 may obtain the position information of the user terminal transmitting the search request and the distance information set by the user of the corresponding user terminal. The position information may be received together with the request in the game service platform server 301 through the corresponding user terminal or in the game service platform server 301 through a separate position information providing system having position information of the corresponding user terminal. The distance information may be set by the user of the corresponding user terminal, such that it is stored in the corresponding user terminal and then received together with the request in the game service platform server 301 through the user terminal or may be received in the game service platform server 301 when it is set by the user, such that it may be stored in the game service platform server 301 in advance.

The game service platform server 301 obtaining the position information and the distance information of each of the first and second user terminals 1310 and 1320 may determine a range for searching the challenge opponents for each terminal based on the position information and the distance information. The position information means a current coordinate of the user terminal, and the distance information means in which a distance of the users of other user terminals to be searched as the challenge opponents are present based on the current coordinate of the user terminal. The range can be variable set to, for example, 5 meters (m), 10 m, 20 m, 50 m, 100 m, 200 m, or the like.

When the distance information is set to 50 m, the game service platform server 301 may search other user terminals present in a radius of 50 m from a current position of the corresponding user terminal. In this case, the user terminals that become search subjects may be user terminals providing the request for searching the challenge opponents through the above-mention motion. When the distance information set by the first user is 50 m and a distance between the first and second user terminals 1310 and 1320 is 5 m, the second user terminal 1320 may be included in other user terminals searched by the game service platform server 301 according to the request of the first user terminal 1310. When, for example, the distance information set by the second user is 15 m and the distance between the first and second user terminals 1310 and 1320 is 30 m, the first user terminal 1310 is not included in other user terminals searched by the game service platform server 301 according to the request of the second user terminal 1320.

The game service platform server 301 may confirm searched other user terminals and provide information on users of the confirmed other user terminals to the user terminals transmitting the request. In the above-mentioned example, the game service platform server 301 may provide information on the user including game related information of the second user terminal 1320 to the first user terminal 1310 according to the request of the first user terminal 1310. The game service platform server 301 may provide information on the user of the first user terminal 1310 to the second user terminal 1320 according to the request of the second user terminal 1320.

When the distance between the first and second user terminals 1310 and 1320 is 20 m, the game service platform server 301 may confirm the second user terminal 1320 according to the request of the first user terminal 1310 and provide information on the user of the confirmed second user terminal 1320 to the first user terminal 1310. However, since the distance information on the second user terminal 1320 is 15 m, the first user terminal 1310 is not searched with respect to the request of the second user terminal 1320.

FIG. 14 illustrates a method for searching neighboring game battle opponents according to position information and distance information according to exemplary embodiments of the present invention. A first arrow 1410, a second arrow 1420, and a third arrow 1430 simply indicate uni-dimensionally positions according to position information of a user terminal A, a user terminal B, and a user terminal C, respectively. A first dotted parabola 1440, a second dotted parabola 1450, and a third dotted parabola 1460 indicate searchable ranges of other user terminals according to distance information of the user terminal A, the user terminal B, and the user terminal C, respectively.

In FIG. 14, for the user terminal A, only the user terminal B is included in the searchable range as illustrated by first dotted parabola 1440. For the user terminal B, both of the user terminal A and the user terminal B are included in the searchable range per second dotted parabola 1450. For the user terminal C, a user terminal included in the searchable range is not present per third dotted parabola 1460.

Per FIGS. 13 and 14, the game service platform server 301 may provide various information on the user of the user terminal B as the search result to the user terminal B, with respect to the request generated according to the motion of the user terminal A. Likewise, the game service platform server 301 may provide information on the users of the user terminal B and the user terminal C as the search result to the user terminal B, with respect to the request generated according to the motion of the user terminal B. However, the game service platform server 301 may notify the user terminal C that a search result is not present, with respect to the request generated according to the motion of the user terminal C.

When the information on the user of the user terminal B is selected in the user terminal A and the information on the user of the user terminal A is selected in the user terminal B, the game service platform server 301 stores information on the users of the user terminal A and the user terminal B in interconnection with each other, thereby making it possible to set the users of the user terminal A and the user terminal B to the challenge opponents to each other to play the game.

The game service platform server 301 may also perform a uni-directional challenge opponent search. When the information on the user of the user terminal C is selected in the user terminal B, even though a search user terminal is not present in the user terminal C, the game service platform server 301 may transfer a challenge invitation according to the challenge opponent search request of the user terminal B as show in FIG. 9 to the user terminal C, and a challenge relationship between the users of the user terminal B and the user terminal C may be set according to acceptance of the challenge by the user terminal C.

The game service platform server 301 may search other user terminals by further using at least one of a local time of the user terminal when the user terminal transmits the request according to the motion and an arrival time when the request is received in the game service platform server 301. For example, when the first user terminal 1310 transmits the request generated according to the motion thereof at 3:3:15 and the second user terminal 1320 transmits the request generated according to the motion thereof at 3:3:16, a difference in a local time between the first and second user terminals 1310 and 1320 is 1 second. When an arrival time at which the request of the first user terminal 1310 is received in the game service platform server 301 is 3:3:20 and an arrival time at which the request of the second user terminal 1320 is receive in the game service platform server 301 is 3:3:23, a difference in an arrival time between the first and second user terminals 1310 and 1320 is 3 seconds. The game service platform server 301 may search the first or second user terminals 1310 or 1320 as the subject user terminal only when the difference in the local time is a preset difference value or less or the difference in the arrival time is a preset difference value or less. Exemplary preset difference value can range from mere seconds to minutes to hours, or even days.

The local time or the arrival time may be used when the position information of the user terminal is not accurate, such as the interior of a room, and the preset difference value may be set to be adjusted according to an error range of the position information. In terms of the first user terminal 1310, when the preset difference value is 2 seconds and the difference in the local time is used, since the difference in the local time is 1 second, the second user terminal 1320 may be searched according to the request of the first user terminal 1310. However, when the preset difference value is 2 seconds and the difference in the arrival time is used, since the difference in the arrival time is 3 seconds, the second user terminal 1320 is not searched according to the request of the first user terminal 1310. In order to correct accuracy for the position information of the user terminal, the local time or the arrival time may be used. The difference value in the local time and the difference value in the arrival time may be different from each other and be set by the user.

FIG. 15 illustrates a method for searching neighboring game battle opponents according to position information, distance information, and a time according to exemplary embodiments of the present invention. A first arrow 1510, a second arrow 1520, and a third arrow 1530 simply indicate uni-dimensionally positions according to position information of a user terminal A, a user terminal B, and a user terminal C, respectively. A dotted parabola 1540 indicates searchable ranges of other user terminals according to distance information of the user terminal B. Time values represented at upper portions of the first arrow 1510, the second arrow 1520, and the third arrow 1530 indicate local times of the user terminal A, the user terminal B, and the user terminal C, respectively. It is assumed that a preset difference value in the time in this example is 3 seconds.

When only the position information and the distance information are used, in terms of the user terminal B, both of the user terminal A and the user terminal C may be searched according to the request of the user terminal B. However, when it is judged that accuracy of the position information is a preset value or less, information on at least one of the local time and the arrival time may be further used. In this case, since a difference in the local time between the user terminal B and the user terminal C, which is 5 seconds, is larger than the above-mentioned difference value, which is 3 seconds, the user terminal C may be excluded from the search. In order to compensate for the accuracy of the position information, the information on the local time or the arrival time may be used.

Again referring to FIG. 13, the game service platform server 301 according to the exemplary embodiment of the present invention described above has used the distance information set by the user. However, a game service platform server 301 according to another exemplary embodiment of the present invention may also use distance information preset to a default. For example, the game service platform server 301 may also search only other user terminals present in 10 m from the user terminal. Also in this case, searched user terminals may be limited to user terminals transmitting the request according to the motion. In this case, the game service platform server 301 according to another exemplary embodiment of the present invention may further use information on at least one of a local time when the user terminal transmits the challenge opponent search request according to the motion thereof and an arrival time when the request is received in order to ensure accuracy of the position information.

The game service platform server 301 according to various exemplary embodiments of the present invention may search other user terminals during a time according to the above-mentioned difference value after an initial request of the user terminal and provide information on the users of searched other user terminals to the user terminal transmitting the initial request. In this case, the game service platform server 301 may provide the information on the users of the user terminals searched until the time according to the above-mentioned difference value at a time after the time according to the above-mentioned difference value elapses or continuously provide the information on the users to the user terminal every preset update time such as every one second or every two seconds until the time according to the above-mentioned difference value elapses. The update time may be determined and used in order to decrease a waiting time of the user to decrease boredom of the user.

The search result may be provided to the respective user terminals as shown in FIG. 7C. Therefore, the user selects at least one user in the list of the searched neighboring persons as the challenge opponent and progresses the challenge for the corresponding game.

FIG. 16 illustrates a procedure of searching game challenge opponents based on an action of a user according to exemplary embodiments of the present invention. Referring to FIG. 16, when at least one search menu for selecting the challenge opponents is provided to the user terminal (S1601), the user selects the corresponding search menu to search the game challenge opponents. When the “challenge to neighboring person” is selected (S1602), a guide message such as “simultaneously shake phones”, or the like, as shown in FIGS. 7B and 13 is displayed. In this case, when the user terminal is shaken or bumped against another user terminal, the user terminal senses the motion (S1603) and performs the challenge opponent search for the neighboring users.

The user terminal transmits the information (for example, motion sensing time information) on the motion (or the action) and the position information (for example, latitude and longitude information) of the user terminal to the server, the game service platform server (S1605). The game service platform serve searches information on adjacent user terminals using the action information and/or the position information collected from the respective user terminals as described above. In this case, the game service platform server may search the user terminals simultaneously moved at adjacent positions or search all user terminals positioned at adjacent positions.

The search result is again transmitted to the user terminals that have been moved, and the user terminals receive the transmitted search result (S1606) to display the search result as a list as shown in FIG. 7C. When the search result is not present according to the received information (S1607), a re-search may also be performed (S1609). When the search result is present according to the received information, at least one user in the list is selected as the challenge opponent (S1608), and the challenge invitation is transmitted to the user terminal of the selected user (S1610), such that the game challenge is proposed.
